Forum: web Subject: Forum entries disappearing - important

Hi,

Can someone explain why forum postings would disappear?

Some months back I posted a note about Boeing's Solar Power Tower page having disappeared, I then came here and asked about it. I got a couple of responses explaining how to searh the Way Back Machine and I subsequently found the archived version here: http://web.archive.org/web/*/http://http://www.boeing.com/assocproducts/energy/powertower.html

Now, when you google for "Boeing Solar Power Tower" the first two hits are archive.org forum links:
http://www.archive.org/iathreads/post-view.php?id=49245
http://www.archive.org/iathreads/post-view.php?id=54445

However, they no longer exist at archive.org

How come?

(be sure to see my "p.s." at the end of this posting.

Cheers,
Andrew

Here's the text of the missing forum entries (from Google cache):

---------------- snip ----------- snip ------------------
Boeing used to have a very comprehensive and informative website about their Solar Power Towers (cost effective, simple and practical technology, could have built a thousand of them for the $200 billion spent on the war so far, etc.).

The site was here (at least a couple of months ago):
http://www.boeing.com/assocproducts/energy/powertower.html

And now has gone bye-bye.

I have send an email to Boeing asking about it.

In the mean time, how can I find out if it has been archived here?

If it has not been archived is there a newsgroup where I can ask someone who may have it, to submit it to the wayback machine?


Thanks,
AJ

You should try entering the URL ( <http://www.boeing.com/assocproducts/energy/powertower.html> ) in the Wayback Machine lookup box. (This box appears on the www.archive.org homepage and the web-collection page, <http://www.archive.org/web/web.php>.)

You can also use the Wayback Machine 'bookmarklet' offered on the web-collection page -- it will look-up whatever URL your browser is currently viewing. So you could visit the Boeing page, see their error, then click the bookmarklet, and any archived versions of the page will be shown. (Note that sometimes a website redirects an error/missing-page to a different URL, so the bookmarklet isn't as useful as typicing the URL directly).

Hope this helps,

Thank you. It's there in the archive, wonderful.

I also received a reply back from Boeing. The Boeing Power Tower technology went to United technologies (Pratt & Whitney) with the sale of Rocketdyne earlier this year.

Unfortunately, neither the UTC nor the P&W site have any reference to the Power Tower technology.

Here's a direct link to the 03/06/2005 version of the Boeing page:

Here's a google search for "Solar Tower Heliostats":

p.s.
Do you know how many 200 megawatt plants like this we could have built for the $200+ billion we've spent so far in Iraq an Afghanistan? About 1000 of them (at $1-2/watt), definately more as we gained economies of scale and evolved plant design. Do you know how many people that would have employed right here in the US of A? How technological research it would have spawned?

Do you know how many barrels of oil equivalent those plants would generate each and every day? One million. Yes that's right, more than we currently get out of Iraq.

The point being, that anyone googling for "Boeing Solar Power Tower" would find the archive.org forum links, which would then lead them to the archived Boeing page.

But with the broken forum links this no longer works.

So, once again anyone searching for "Boeing Solar Power Tower" won't find anything.

Fascinating.

Cheers,
Andrew

FYI, we had a minor problem for a few hours with forums
when I was attempting to improve some DB caching.
As you noticed, fixed now!

Not sure if this helps with your fixes / debugging but I had noticed the missing links on and off for several weeks now.

Thanks again for the quick response.

hey!

yes, a bunch of us on staff had, too (good eyes! 8-)
but i'd been unable to track it down.

the other fixes i did may have fixed it (a bit hard to say,
but i'm semi hopeful) so i'll be watching for that problem
if it pops up again.

so basically there were 2 bugs:
1) sometimes forum posts weren't showing up (for 1-2+ weeks)
2) yesterday nearly *all* the forums went "gone" after a DB table got partially corrupted. that got fixed within a few hours.

--t!
